ING- COMPANY, OF MIAMI, FLORIDA., A CORPORATION OF FLORIDA.

CASEMENT-WINDOW OPERATOR.

Application led December 26, 1922. SerialLNo. 609,047.

To all whom t may concern:

Be it known that I, ROLAND B. WORTH- ING'roN, a citizen of the United States, residing at Miami, in the county of Dade and State of Florida, have invented certain new and useful Improvements in Casement- Window Operators; and I do declare the following to be'a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usevthe same.

My invention relates to easement window operating and locking devices, and particularly those which operate through or beneath the window screens.

In one form of easement window operators of the type employing an arm pivoted to the swinging window and passing slidably through a casing which is received in a notch in the lower end of the usual winf dow screen, the upper section of the casing is rotatably mounted to turn with the window operating arm as the latter is moved inwardly or outwardly, but it often happens that swelling of the screen will bind the walls of its notch against the rotary casing section and -will therefore interfere with proper operation of the device. Furthermore, the casings to which I refer, have occupied a great deal of space upon the window sill and have extended both inwardly and outwardly from the screen, which is not only unsightly but often objectionable when the screen is very close to the window sash.

It is one of the objects of the present invention to provide a device which will be free from the above mentioned objections, will be simple-and inexpensive to manufacture, will be strong and durable, and will be exceptionally easy to apply to practically all kinds of Casement windows. Y l

In carrying out the vabove'ends,A a relatively long and narrow casing is secured horizontally upon the window sill to be snugly received in a rectangular notch in the lower end of the screen, opposite sides of this casing being provided with slots through which the window operating arm extends to be engaged by arm-holding means within the casing. The slots are of such length as to permit the necessary horizontal swinging of the window operating arm, yet the entrance of insects through these slots is prevented by a novel arrangement of parts.

With the foregoing in view, the invention resldes in the novel subject matter hereinafter described and claimed, the description bemg supplemented by .the accompanying drawings.

Figure 1 is ahorizontal sectionalview showing the application of my invention to a screened easement window, vthe window being closed.

Figure 2 is a dpulicatevof Fig. 1 with the exception that it discloses the window heldin an open position. v

Figure 3 is an enlarged top plan view ofthe casing and a portion of the arm which passes therethrough.-

Figure 4 is a horizontal4 sectional view through the casing showing the internal parts thereof in elevation.

Figure 5 is a dpulicate of Fig. 4 but disclosing a different relation of parts.

Figure 6 is a longitudinal sectional view as indicated by line 6-6 of Fig. 3.-

Figure 7 is a vertical transverse sectional view on line 7-7 of. Fig. 6.

Figure 8 is a detail sectional view as indicated by line 8 8 of Fig. 3.

Figure 9 is-a perspective view of the barrier plate which prevents insects from passing through a portion of the casing.

Figure 10 is a persspective view of the slide which in the present embodiment of the invention, prevents insects from entering through the channel of the operating arm.

In the drawings above briefly described, the numeral 1 designates a easement window, 2 has reference to the window frame having the usual-sill 3, and 4 indicates an appropriate sliding or 4swinging screen spaced inwardly from the window;

An operating arm 5 which is preferably of channel form, is suitably pivoted .at 6 to a bracket secured to the window 1 and while its outer portion is preferably curved, its inner end will in most instances be straight to lie above the sill 3 when the window is closed as shown in Fig. 1. This of positions and it will be seen by reference to Fig. l that one of these notches may co-act with a stud 9 suitably attached to the window sill 3, for the purpose of hold- Vhave longitudinal slots 12 near one end through which the arm 5 passes and the sides are preferably disposed in the planes of the side faces of the screen frame so that the casing will not project laterally beyond the same. W'ithin the casing 10, I provide a suitable stop which is preferably in the form ofan upright post 13 for co-action with the notches 8 to hold the window in different adjusted positions. The edgeof the arm 5 opposite the notches 8, lis engaged by a roller 14 on the end of a plunger 15 which is longitudinally movable in the casing 10,v an appropriate coil spring 16 being employed to force said plunger in` a direction to effect engagement of an arm notch 8 with the post 13, when the arm is adjusted to any pre vdetermined position.

In the construction shown, the casing 10 is provided with a rectangular base plate 17 having openings 18 in its ends to receive attaching screws 19, ,this plate and the parts 13, 14, 15 and 16, being entirely covered by the top and vertical sides of the casing as shown. The base plate 17 preferably carries all parts of the device except the arm 5. In the present showing, the post 13 is secured to the plate 17 as indicated at 20 in Fig. 6, the body portion of the plunger 15 rests on said plate and is held in proper position thereon by an arched bearing 21 securedto said plate, and another bearing 22 rises from this same plate to guide a stem 23 which is surrounded by the spring 16 and forms a part of the plunger. The casing may well be secured at one 4end to the bearing 22 and at its other end to the post 13, for which purpose I have shown screws 24. The casing top is formed with a pair of openings 25 giving access to the screw holes 18 and it will thus been seen that the casing and parts contained therein maybe sold in an assembled condition and need not be disassembled to any extent whatever when applying to the window sill, it being simply necessary to drive the screws 19 by passing them2a5nd a screw driver through the openings In order to permit the necessary horizonneoaiaa tal angling of the operating arm 5, the slots 12 are rather long. Provision is Amade however to prevent insects from entering the building through these slots. In the present showing, I have illustrated a longitudinally disposed barrier wall 26 rising from thev base plate 17 and extending from the post 13 toward the adjacent end of the casing 10, Jrhe end of the wall which abuts said post, being preferably thinned as indicated at 27, to interfere in no manner with proper engagement of the notches 8" with said post. This prevents insects from seeing light and entering at the notched edge of the arm 5 and the plunger 15 performs a similar function at the opposite edge of said arm 5. The insects are prevented from entering through the channel of the operating arm 5, by means of a flange 28 which depends from a horizontal slide plate 29, this plate being positioned over the plunger '15 and connected therewith by any suitable means, such as an upstanding pin 30 on the plunger received in an opening 31 in the plate. 'Ihis plate 29 preferably rests slidably upon the bearing 20 and upon the wall 26 and may Well be formed with a slot 32 receiving the upper end of the post 13.

While such an arrangement has not been shown, it would of course be possible to provide the sliding plate 29 with some form of depending liange which would perform the same function as the barrier wall 26.

By providing the construction shown or a substantial equivalent thereof, a device is provided which may be easily and inexpe'nsively manufactured, which may be applied with ease by unskilled labor, and may be very conveniently and easily operated. It may be explained that as the distance between the window and the screen is not always uniform, it would not be advisable to have the arm 5 engage the post 13 for locking the window closed, as this would necessitate an accurate positioning of the casing 10 upon the window sill and would not inl all cases permit the disposition of this casing in a notch in the screen. Hence, I provide the additional fastening stud 9 which may be secured to the sill at any desired point, regardless of where the casing is located. This stud,`r it will be `noted, co-acts with one of the notches 8 so that it is unnecessary to provide an additional notch or to yrecess the opposite edge of the arm 5 which is thus left smooth for free sliding engagement with the antifriction roller 14.

As excellent results have been obtained from the details disclosed, they are preferably followed. However, within the scope of the invention as claimed, numerous minor changes may be made. i
